I had renamed the original version of wi_sph.dll to wi_sph.dll.old and replaced it with wi_sph.dll from the zipped update, Explorer shows 1.1.0.160 as the version number for the latter file. Looking back the only slightly odd thing during the process was that Explorer changed the capitalization of the file from WI_sph.dll to wi_sph.dll but I assumed that wouldn't make any difference. I'm not sure where Pegasus got the old version number from once the files had been replaced with the newer versions - perhaps I should have deleted the old files completely rather than just changing their extensions?
